Cuisine & Edibility

Arapaima

Large, firm white fillets with a mild, clean flavor and low fat; historically a staple protein in Amazonian communities. Often salted and dried; sustainable harvest is tightly regulated.

Yellowfin Tuna

Lean, dense flesh with a clean, meaty flavor; prized for sashimi and poke. Excellent seared rare, grilled as steaks, or served raw; one of the most commercially valued tunas.

Species Overview

Arapaima

The arapaima is one of the largest freshwater fish in the world, reaching up to 4.5 meters. An obligate air-breather, it must surface every 10-20 minutes to gulp air. Its tongue is bony and used to crush prey against the roof of its mouth.

Yellowfin Tuna

The yellowfin tuna is a pelagic predator found in tropical and subtropical oceans worldwide. Capable of speeds exceeding 75 km/h, it is prized both as a sport fish and for its high-quality sashimi-grade flesh.
